Most commonly used mills for coal grinding in cement plants are closed circuit air swept (Single chamber) ball mills and verticalmills. Ball Mill: Single chamber ball mills (with classifying liners and dam ring) with drying chamber and static or dynamic separator are commonly existing forcoal grindingin cement plant for one or more kilns as per capacity.
